Mastering Histamine Intolerance and
Mast Cell Activation Syndrome (MCAS): 

A Complex Illness Specialist’s Guide

Beyond ‘managing’ histamine - expanding your capacity so you can increase the scope of your life

Dr. Brian Lum is a board-certified functional medicine practitioner (IFMCP) as well as a complex illness specialist.  For over a decade, he has sought the most complex patients who were not responding to conventional treatment or whose collections of symptoms did not have a diagnosis. 

Using the latest scientific advancements and diagnostic tools, he crafts individual treatment plans using clinical-grade supplementation and nutritional guidance.

The Histamine Problem

Identifying the common Issue

Dr. Lum noticed that most of his patients had a histamine component to their chronic illness and that the typical approach to healing histamine issues did not have a high success rate.

In this course

Using his specialized knowledge, Dr. Lum will address the top myths keeping you from getting better and outline the game-changing interventions to help you heal naturally. 

The key to getting rid of histamine-related issues lies in two things:

  • The specificity of treatment

  • The 'order of operations' in which those treatments are administered. 

In this online-course format, Dr. Lum can help you chart a path forward out of ambiguous treatment options and the overly restrictive yet ineffective dietary interventions.

The common treatment gap

Why Doesn't Treatment for Histamine Intolerance or MCAS usually work?

Most approaches for Histamine Intolerance/MCAS rely on a series of assumptions (covered in this mini-course) that result in limited effectiveness. There is also a damaging underlying insistence that histamine intolerance is something to be managed - not something to be resolved completely.​

Complete symptom resolution is a common occurrence in this practice. By specializing in hard-to-treat patients, Dr. Lum learned that everyone is capable of healing completely and that the vast majority of patients who have been told to 'just live with' symptoms have not been fully medically investigated.

This mini course is designed to give you real-world solutions that you can apply, specific tests that your doctor can order, and supplements that have been effective for our patient base.

Importantly, it will also change the way you think about Histamine-related symptoms.

How will Dr. Lum's 'Mastering Histamine' Course Help Me?​

Dr. Lum distills all the most relevant information about Histamine-related symptoms in this course. It aims to empower the patient with knowledge to navigate future doctor's appointments and to know what treatments have actually made a difference in other patients healing trajectory. ​

​The key to getting rid of histamine-related issues lies in the specificity of treatment and the 'order of operations' in which those treatments are administered. 

In this online-course format, Dr. Lum can help you chart a path forward out of ambiguous treatment options and endless, overly restrictive diets.​​

How is Dr. Lum's Mastering Histamine Course Different from other courses?

There are many other Histamine-related courses and protocols. The framework of many of these relies on a specific ideology rather than extensive clinical experience or published research.

Dr. Lum's approach is informed by the latest research, which he cites within this course. That research informs his approach to healing Histamine issues within his patient population but is constantly refined based on patient response.

Importantly, his patient base consists of those who are particularly sensitive, so these guidelines are more likely to be tolerated by the majority of the population who have Histamine issues.
